Large party in Melbourne's south-east. 500 teenagers. Police cars damaged.

Bottles thrown at officers. Neighbours scared. Police helicopters and dog squad called in. $20,000 cost to the public. Parents yet to find out.More than 500 teenagers spilled on to the streets, damaging property and throwing projectiles at police cars during the party on Saturday night.

Victoria Police have threatened to bill the homeowners, who were interstate at the time, $20,000 in damages.

And they plan to charge another youth on summons with unspecified offences.

The charged youth will appear at a Children's Court on February 22.

Outside a Victorian police station, where the teenager and another youth were interviewed yesterday, other teenagers said they were at the party and were looking forward to the next one.

"We've heard (one of the youths) is planning another one for next week. It should be pretty good," one girl said.

The charges come after the party's organiser fled Fox FM studios hours earlier during a sometimes hostile interview on live radio, for which the station paid $750.

The teenager bolted out of the studio and fled down a fire escape after host Matt Tilley tried to remove his plastic yellow sunglasses, which are the talk of the online community worldwide. He was chased by several news crews but disappeared.

He later returned to the studio and completed the on-air interview. Before making his escape, the youth was asked if he had anything to say to his parents, who might be listening. "Sorry," he said.

He also said he had been approached by a DJ to run an under-age club in Melbourne.

Listeners to the radio show were overwhelmingly hostile, with one woman telling him he had no respect for anyone else and a man calling him a "knob" and warning him to "watch out".

Austereo Melbourne general manager Ben Amarfio said the station had simply reacted to strong public interest in the story.

"(The youth) advised us that he was also keen to join The Matt & Jo Show , but given the fact he had been offered payment by another commercial radio station, he wanted us to match their offer," he said.
